So what you are proposing is to have all subtrees of the root either hierarchical or not, right? > This seems needlessly complicated. :( Toggle wouldn't help much I am afraid. We would still have to distinguish (non)hierarchical cases. And I am not sure we can make everything hierarchical easily. Most users (from my experience) ignored use_hierarchy for some reasons and the end results might be really unexpected for them if they used deeper subtrees (which might be needed due to combination with other controller(s)). -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.
